JOI-IANN DREOKMANN, OF CASSEL, GERMANY.

SIPHON FOR BEER.

SPECIFICATION forming part of Letters Patent No. 633,341, dated September 19, 1899. Application filed February 8, 1899. Serial No. 704,913. (No model.)

To all whom it moty concern.-

Be it known that I, J OHANN DRECKMANN, engineer, a subject of the German Emperor, residing at Cassel, Germany, have invented a certain new and useful Improved Siphon for Beer and Aerated Drinks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Thisinvention consists of an improved construction of fountain or siphon for drawing beer and carbonated or aerated drinks.

In the accompanying drawings, Figure 1 is a vertical section of my improved siphon. Fig. 2 is a side View of the siphon. Fig. 3 is Fig. 4 is a vertical cross-section through the reduction -valve. Fig. 5 shows the tapping-valve in the position when opened.

The siphon is made in two parts-aliquidcontaining receptacle or vessel A,which may be made of glass or other suitable material, and a pressure-containing vessel B, which is mounted upon the top of the liquid-receptacle and may be conveniently made of metal. These two vessels may be permanently or de tachably united in any suitable way. In the drawings I have shown them as detachably secured together by means of hooks H, pivoted at H to the levers h, which are pivoted at h to the ears 'h, secured to the under part of the vessel B. These levers act as knucklelevers. The books H engage with ears J of a ring J, surrounding the lower vessel A. If the levers h are brought into an upright position, as shown in Fig. 1, the rubber gasket j,

arranged between the vessels A and B,.is compressed and the vessels are held together airtight.

The tapping-valve F is arranged in the easing m and is provided with a stem f, passing through the stufling-box m of the casing. The stem f is screwed into a cross-bar f, the ends of which are pivoted to the arms f. These arms are pivotally connected at f to a double-armed lever g, pivoted at g. The

lever g and the arms f act as knuckle-levers. If the lever g-is in its upright position, as shown in Fig. 1, the valve F is pressed against the end of the rising-pipe m, which is connected with the pipe 0 by the tube 0', fastened to the bottom D of the vessel B and containing a packing-ring 0, which is compressed by the screw-nut 0'. By turning the lever g on its pivot g so that it is brought into the horizontal position shown in Fig. 5 the valve F is opened, so that the liquid contained in the vessel A may flowout through the out let-pipe m of the casing m. By turning the screwed end of the stem of the valve F in the cross-bar f the valve F can be adjusted to the end of pipe m, forming the seat of the valve.

In the upper vessel B is arranged a checkvalve E, opening from the vessel A into the interior of the vessel B. This check-valve consists of a rubber plate 19, which is arranged in the cap 19 and pressed against the upper end of a pipe 19. This pipe is connected to the pipe q, engaging with its lower end'into the packing g, which is arranged in a short tube q, fastened in suitable manner to the bottom D of the upper vessel B. Bya screw-nut q, surrounding the pipe (1, the packing q is compressed, so that this pipe (1 is air-tight, connected with the tube q and the bottom D. The upper vessel B has also a reducing-valve O, which may be of anysuitable construction. In

' the construction illustrated, by way of example, in acasinge, fastened to the top of the vessel B, is arranged a spring-plate a, preferably made of rubber or alike material and strengthened by a metal plate a. To this springplate is fastened a body at, having a rectangular opening, as clearly shown in Fig. 4, and provided, with a rubber plate 0. Into the said opening of the body a reaches a pipe I), fastened to the casing c. This pipe has a passage b, against the lower end of which is pressed the rubber plate 0 of the body a. The upper end of the body (t presses against a rubber plate (1, arranged in a button d',which can be pressed down. The bottom of the easing e is provided with a central opening 2', normally closed bya rubber plate 70, which is pressed against the bottom of the casing e by a cap e, fastened in a suitable manner to the casing c. This rubber plate is provided with several openings 70. To the cap 6 is fastened the pipe 1, engaging with its lower end into a packing l, arranged in the short tube 1, which is fastened in a suitable manner to the bottom D of the upper vessel B. A screw-nut Z surrounds the pipe I and can be screwed into the tube 1, so that the packing 1 is compressed, and an air-tight connection between the pipe Z and the tube Z or the bottom D is obtained.

In filling this fountain or siphon the pressure-gas, such as carbonic acid, is first introduced through the opened tapping-valve F under suitable pressure into the vessel A, and then the liquid is also introduced through the same valve. As the liquid is introduced the air or gas in the vessel A is displaced and passes through the check-valve E into the vessel B, where it is more or less compressed. The liquid in the vessel A is new under a certain pressure. If the valve F is opened for drawing off liquid, the pressure in the pipe I is lowered, and the higher pressure of the gas in the vessel B presses down the body a of the reduction-valve, so that the orifice of passage 1) is opened, and carbonic acid can pass through the opening i and the openings 70 of the rubber plate 7c into the vessel A. If the pressure in the vessel A is not suificient, the button (1' is pressed down, so that also the body (b is pressed down and the passage 1) is opened wider, and a greater quantity of carbonic acid will flow through the pipe Z into the vessel A.

Having now described my invention, what I claim, and desire to secure by Letters Patent, is

The herein-described fountain or siphon comprising two vessels, one a liquid-receptacle and the other a gas-receptacle with a reducing-valve connecting the two and a check-valve opening from the liquid-receptacle into the gas-receptacle, whereby a substantially constant pressure is maintained in the liquid-receptacle while dispensing therefrom, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

JOII ANN DREOKMANN.
